Question

A reaction in which x and y form products was found to be first order in x and zero order in y. by what factor will the rate of the reaction change if [x] is tripled and[y] is held constant?

Answer 1

In zero order reactions the rate of reaction is independent of reactant concentrations. That is the rate of the reaction does not vary with increasing nor decreasing reactants concentrations. On the other hand, first order reaction are reactions in which the rate of reaction is directly proportional to the concentration of the reacting substance (reactants). In this case, i believe the rate of reaction will triple( increase by a factor of 3)
